• Reduce rate of PENETRATION

FILTER CAKE INCREASE with WATER LOSSES increase

Filter cake increase with water losses increase

Ph is the pressure exerted by the weight of a liquid on its “CONTAINER

Ph is the pressure exerted by the drilling fluid to offset the pressure exerted by the formation fluid

Ph (PSI) = 0.007 * TVD (ft) * Mud wt. (PCF)

Ph (PSI) = 0.052 * TVD (ft) * Mud wt. (PPG)

Sufficient HYDROSTATIC pressure is required to prevent the borehole wall from caving in and to keep formation fluid from entering the wellbo

• High viscous MUD to circulate hole cleen
• High viscous mud to put on BOTTOM before TRIP

• Permit to work
• Per job safety MEETING
• ELECTRIC isolation and put safety lock behind pump
• Close discharge valve - open bleed valve -then close suction valve
• CHECK pump and REPLACE parts
• REMOVE tools from pump area
• Open discharge valve-closed bleed valve-open suction valve
• Remove safety lock and isolation
• Cleen cooling tank and fill it
• close work permit

• cool and lubricate the DRILLING bit
• carry cutting from the bottom of the HOLE to the surface
• Drilling mud know as hydrostatic pressure which ALLOW to control
• the formation pressure
• Clean drill bits ,drilling mud removes cutting from bit teeth which
• prevent bit BALL up situation
• prevent formation damage by using suitable drilling mud
• Transmit hydraulic horsepower to the bit
• To avoid bit to balled up
